DESCRIPTION
The VS-MBRS140TRPbF surface mount Schottky rectifier
has been designed for applications requiring low forward
drop and very small foot prints on PC boards. Typical
applications are in disk drives, switching power supplies,
converters, freewheeling diodes, battery charging, and
reverse battery protection.
